 * The sum of the squares of the first ten natural numbers is,

 * 
 * 1#2 + 2#2 + ... + 10#2 = 385
 * 
 * The square of the sum of the first ten natural numbers is,
 * 
 * 
 * (1 + 2 + ... + 10)#2 = 55#2 = 3025
 * 
 * Hence the difference between the sum of the squares of the first ten natural
 * numbers and the square of the sum is 3025-385 = 2640.
 * 
 * Find the difference between the sum of the squares of the first one hundred
 * natural numbers and the square of the sum.
